No. If you mean just a normal pressure tank for rural residential, no I live in town, but we have good water pressure. But, I thought it was a closed system with water only being added when need be. I think I am misunderstanding you.

I was going to have a pump drawing water from the bottom of the 2nd in line tote. The water would be pumped to the biofilter (drum) then routed to the first tote then 2nd. All water would be dumped into the top of each container and drawn out the bottom.
